Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 2 and Fig. 3, in this embodiment, the magnet arrangement of the utility model injection machine automatic mold-adjustment locking device 100 is tractive magnets, it is commercially common product, can the size of tractive force be as required convenient selects various model, such as, product type is SA-4602 (specification: tractive force 8Kg, stroke 30mm), many limit-line stores comprise Taobao store and can buy.The utility model automatic mold-adjustment locking device 100 mainly comprises tractive magnet 7, latch guide plate 4 and mode transfer wheel gear locking tooth 3.Mode transfer wheel gear locking tooth 3 comprises locking teeth part 31 and horizontal cross bar 32, and one end (being right-hand member in figure) of locking teeth part 31 is provided with horizontal cross bar 32, and horizontal cross bar 32 is connected with the kinetoplast 71 of tractive magnet 7.In this embodiment, horizontal cross bar 32 is connected by a rivet with the electromagnet towing plate 6 of the kinetoplast 71 of tractive magnet 7.Above-mentioned electromagnet 7 is arranged on mount pad 8.
Be provided with a horizontal guide slot in latch guide plate 4, horizontal cross bar 32 is placed in move horizontally (slip) in this horizontal guide slot, and like this, locking teeth part 31 also can along with moving horizontally.Latch guide plate 4 and mount pad 8 are fixedly linked by screw 15.
Be provided with check lock lever guide rod 1 at the other end (being left end in figure) of locking teeth part 31, back-moving spring 11 is enclosed within also can horizontal compression and stretching, extension on check lock lever guide rod 1.The left end of check lock lever guide rod 1 is provided with plush copper 41, and right-hand member is provided with spring base 2.The right-hand member of back-moving spring 11 contacts with spring base 2 and is blocked by it, left end is blocked by plush copper 41, and such back-moving spring 11 can compress between spring base 2 and plush copper 41, is provided with a hole in the middle of spring base 2, check lock lever guide rod 1 is through in this hole, like this, when check lock lever guide rod 1 receives External Force Acting and moves right, spring 11 is compressed by left end spring base 2, storage power, once external force loses, spring 11 stretches, and is moved to the left so promote check lock lever guide rod 1.
In this embodiment, position detecting switch device adopts proximity switch 14.Proximity switch installing plate 13 is arranged on the top of latch guide plate 4 by screw 29, and proximity switch 14 is fixedly mounted on proximity switch installing plate 13 by screw 28.Proximity switch 14 can adopt induction type proximity switch common on market.In this embodiment, the moving contact of display mode transfer wheel gear locking tooth 3 adopts a screw 12, a such as hexagon socket cap head screw, it is fixed on mode transfer wheel gear locking tooth 3 by the corresponding small opening on proximity switch installing plate 13 and latch guide plate 4, and its upper end is exposed latch guide plate 4 and can close to so that proximity switch 14 is sensed its position with proximity switch 14.When mode transfer wheel gear locking tooth 3 level moves left and right, screw 12 can be toward or away from proximity switch 14, and like this, proximity switch 14 can respond to movement and the position of mode transfer wheel gear locking tooth 3.When respond to mode transfer wheel gear locking tooth 3 arrive the second place (near) time, show that the locking teeth part of mode transfer wheel gear locking tooth 3 and adjustment nut 19 are with safety trip.Now, proximity switch 14 can send the signal of telecommunication with display now can safe mode transfer.
See Fig. 2 to Fig. 5, by description above, can find out, when not needing mode transfer, the power supply of the mode transfer key (power switch) on injection machine guidance panel is in off-state, and electromagnet 7 does not work; Now, mode transfer wheel gear locking tooth 3 engages (see Fig. 4) with mode transfer gear 19.Like this, when the normal mode transfer of needs, press the mode transfer key (power switch) on injection machine guidance panel, electromagnet 7 obtains electric work, electromagnetic attraction makes kinetoplast (drawing head) adhesive of electromagnet, drawing head band motor magnet towing plate 6, check lock lever guide rod 1, horizontal cross bar 32 move right, and horizontal cross bar 32 slides to the right in latch guide plate 4, the locking teeth part 31 of mode transfer wheel gear locking tooth 3 also in latch guide plate 4 (below) slide to the right.As shown in Figure 5, mode transfer wheel gear locking tooth 3 moves right and puts in place, just throws off with the tooth on mode transfer gear 19.Now, the screw 12 be fixed on mode transfer wheel gear locking tooth 3 also moves to desired location, namely after the second place, proximity switch 14 senses the position of screw 12, thus sense that mode transfer wheel gear locking tooth 3 reality arrives desired location (being in safety trip state with the tooth on mode transfer gear 19), so exporting the signal of telecommunication to controlling computer, now just can operate mode transfer advance and retreat button, realizing the normal mode transfer action of injection machine.
After mode transfer release, mode transfer key lost efficacy, and now, make electromagnet 7 dead electricity, the thrust of spring 11 makes check lock lever guide rod 1 move to left, and makes the locking teeth part 31 of the mode transfer wheel gear locking tooth 3 be fastened on check lock lever guide rod 1 realize sliding in latch guide plate 4 left.As shown in Figure 4, mode transfer wheel gear locking tooth 3 moves to left and puts in place, just engages with the tooth on mode transfer gear, so just, lockable mode transfer gear 19, prevent from rotating, also just effectively prevent the automatic pine of rear pattern plate from moving back, thus cause the phenomenon of mould not tight, generation moulding waste product.As can be seen here, the utility model injection machine automatic mold-adjustment locking device is easy to use, and structure is simple, practical.
By description above, essence of the present utility model is that the present inventor pulls moving horizontally of mode transfer wheel gear locking tooth 3 by studying ingenious employing by the suction of simple magnet arrangement, it is made to be in two positions: to engage with mode transfer gear 19 at primary importance mode transfer wheel gear locking tooth 3, can not mode transfer; Throw off at primary importance mode transfer wheel gear locking tooth 3 and mode transfer gear 19, the normal mode transfer of malice.On the basis of above-described embodiment, those skilled in the art can do following change and adjustment still can realize the purpose of this utility model:
1. magnet arrangement is except adopting tractive magnet, can also adopt general permanent magnet;
2. position detecting switch device is except adopting inductive proximity switch, can also adopt conventional contact-making switch.
3. position detecting switch device also can save, and by artificial observation, determines whether mode transfer wheel gear locking tooth 3 engages with mode transfer gear 19 and throw off.
4. horizontal cross bar 32, locking teeth part 31 and check lock lever guide rod 1 can be partly or entirely integrated.
The above; it is only the better feasible embodiment of the utility model; therefore interest field of the present utility model can not namely be limited to; concerning those of ordinary skill in the art; such as use the technical solution of the utility model and know-why to make other to change accordingly and distortion, and used these change and distortion all should belong within the protection domain of the utility model claim.
